Final answer:
Sandel's position on moral reflection being done publicly rather than privately is false; moral philosophy encourages open debate and discussion to foster well-reasoned ethical considerations.
Step-by-step explanation:
The assertion that Sandel argues for more moral reflection to be done in private is false. In fact, the exploration of moral philosophy suggests an emphasis on public discussion, critical examination, and collective reasoning when addressing moral issues. Philosophers like Hume and Anscombe grappled with the role of sentiments and theistic underpinnings in the understanding of morality, with the latter critiquing modern philosophy's lack of firm foundations for ethical 'oughts'. Plato proposed that truth in ethics requires serious contemplation and discourse. Furthermore, engaging in a dialectical process, as suggested by the Post Modern Dialectical Process, involves publicly examining and debating the reasons, principles, and values underlying moral beliefs, in order to establish consistent and coherent reasoning for moral actions.
